Mike,

Thanks for looking at the patch :).

I will revert the change for now, but I will also ask the FSF what
they want us to do. We were told explicitly that all files that
were GPLv2 or later should have been switched to GPLv3 or later.
One tiny change in the copyright header should be manageable, IMO,
particularly since you're already going to see a yearly change in
the copyright years as well.

I don't understand exactly the status of this file. Can I just
regenerate the "reverted" version and the project will still work?

Yes, it was a script based conversion (or rather, perl one-liners).
But I used a regexp that verified that we had the option of switching
to a later version of the GPL. I scanned a large number of the changes,
but I did not check each one of them individually.
